BIOL 2200 PATHO WEEK 3: CASE STUDY 2 LATEST UPDATE GRADED A+ Describe the difference in the histology of the tumour if it had been assessed as a adenoma rather than adenocarcinoma An adenoma is a benign tumour: lost ability to control proliferation the growth is slow the cells are still well differentiated and organized, they also do not invade beyond their capsule do not metastisize. An adenocarcinoma is a malignant tumour: more rapid growth rate loss of differentiation and no lo...

what is cancer characterized by? abnormal cell growth and division what happens when cell growth and proliferation stops being highly regulated? form a mass of tissue (tumour) tumours can be benign or malignant what is the difference? - benign (wrong place wrong function no abnormal outcome) - malignant (impair cell function and have adverse effects) what are precancerous conditions (premalignant cells) abnormal cells that may develop into cancer if aren't treated what are the outcomes of p...
